DS2252T Product details

DESCRIPTION
The DS2252T is an 8051 compatible microcontroller based on nonvolatile RAM technology. It is designed for systems that need to protect memory contents from disclosure. This includes key data, sensitive algorithms, and proprietary information of all types. Like other members of the Secure Microcontroller family, it provides full compatibility with the 8051 instruction set, timers, serial port, and parallel I/O ports. By using NVRAM instead of ROM, the user can program, then reprogram the microcontroller while in–system. This allows frequent changing of sensitive processes with minimal effort. The DS2252T provides an array of mechanisms to prevent an attacker from examining the memory.

FEATURES
• 8051 compatible microcontroller for secure/sensitive applications
    – 32K, 64K, or 128K bytes of nonvolatile SRAM for program and/or data storage
    – In–system programming via on–chip serial port
    – Capable of modifying its own program or data memory in the end system
• Firmware Security Features:
    – Memory stored in encrypted form
    – Encryption using on–chip 64–bit key
    – Automatic true random key generator
    – SDI Self Destruct Input
    – Improved security over previous generations
    – Protects memory contents from piracy
• Crashproof Operation
    – Maintains all nonvolatile resources for over 10 years in the absence of power
    – Power–fail Reset
    – Early Warning Power–fail Interrupt
    – Watchdog Timer
    – Precision reference for power monitor
• Fully 8051 Compatible
    – 128 bytes scratchpad RAM
    – Two timer/counters
    – On–chip serial port
    – 32 parallel I/O port pins
• Permanently powered real time clock
